Mechanism
Continuous Heavy Grazing, introduction of a seed source of exotics like bermudagrass, tall fescue, Johnson grass, dallis grass, whitetop and thistle.
Mechanism
Continuous Heavy Grazing, introduction of a seed source for mesquite, juniper, tree of heaven, Chinese elm, Russian mulberry and or salt cedar.
Mechanism
Poor condition watershed areas produce excess amounts of runoff causing channels to erode. As channels deepen stream terraces no longer flood. Trees and large shrubs still dominate. Perennial herbs are replaced by annuals and half shrubs. Base level change in main stream causes down-cutting of bottoms. Poor condition watersheds can also deliver large amounts of sediment to bottoms, destabilizing them and causing new channels to cut through the floodplain. Poorly designed stream crossings, bridges or culverts can cause small areas of this state.
Mechanism
Unknown. Possible herbicide treatment of exotics species and seeding of native grasses.

Mechanism
Prescribed Grazing/No Grazing of watershed areas with or without shrub control and planting of native grasses, maintenance treatments for shrubs, etc. Mechanical control of sheet, rill and gully erosion here possible. Reestablish flooding regime of bottoms.
